Improved fanning-mill



UNITED STATES PATENT OFFICE.

J. K. BUCK, OF WINONA, MINNESOTA.

IMPROVED FANNI NG-MILL.

To aZZ whom it may concern:

Be it known that I, J. K. BUCK, of Winona, Winona county, and State of Minnesota, have invented certain new and useful Improvements in Fanning-Mill's for Cleaning Grain; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings making part of this specification, and to the letters of reference marked thereon.

Figure 1 is a side elevation of my machine, with a portion broken away for the purpose of showing more clearly my improvements.

Fig. 2 is a transverse horizontal section taken in the line :10 as of Fig. 1.

The nature of my invention consists in providing ordinary fanning-mills with an elevator, so arranged that when the grain has been cleaned it shall be delivered to the elevator, which then carries it up and delivers it through a spout into the bag or sack, ready for market or use.

To. enable others skilled in the art to construct and use my invention, I will proceed to describe it.

A represents the body of the mill, which may be any of the various kinds made, though I have here shown and contemplate the use of the mill patented to me July 23, 1861.

B represents an ordinary strap-and-bucket elevator, applied to the side of the mill, in the manner shown, and properly incased, the up per end of the casing being provided with a spout, G, into which the grain is emptied from the bucket 13. The power is applied to the driving gear-wheel a,which operates the wheel 0 on the fan-shaft in the ordinary manner. Another wheel, I), (shown in dotted lines,) is mounted upon the end of a shaft, 0, which extends across the machine, and has secured to its opposite end the pulley cl, over which the elevator-strap passes. The wheel b is located so as to be driven by the wheel a, as clearly shown in Fig. 1.

In Fig. 2, E represents the screen, from which the cleaned grain finally passes and falls into spout 0, which extends entirely across the machine, underneath the front end of screen E. The spout o'is inclined laterally of the machine, and has its lower end passing through the side of the case A and opening into the lower portion of the elevator-ease, as shown in Figs. 1 and 2.

Another spout or box, m, is placed immediately in the rear of spout 0, and is inclined in an inverse direction, whereby the screenin gs and foul stuff which pass through the screen E are caught, andmay be removed or taken out by raising the sliding-door c.

It is obvious that the spout 0 may be so arranged or modified as to deliver the grain at any desired height or point.

The operation is as follows: Grain being supplied and the mill set in motion, the grain is cleaned in the usual manner, until it is delivered from screen E into spout0,from whence it flows into the elevator-box. It is then raised by the elevator and emptied into spout G, from whence it falls into a bag or other receptacle placed to receive it. By this means all shoveling and after-handling of the grain to get it into bags is entirely avoided, and much time and labor are thereby saved.

It is obvious that the parts may be differently arranged and still made to operate substantially as described. In applying this improvement to mills made differently from my own, it may indeed become necessary to arrange the gearing or other parts differently, and therefore I do not intend to confine myself to the exact arrangement of the parts as herein shown, as that would limit the application of my improvement. 1

Having thus fully described my invention, what Iclaim as new therein, and for which I desire to secure Letters Patent, is-

The combination of the elevator B and shaft 6, provided with the pulley d and wheel I), with the driving-wheel a, when all the parts are arranged to operate as and for the purpose herein set forth.

J. K. BUCK.
